1 Claim. (0. 4-43) This invention relates to an improvement in sired, be supported by suitable braces 6 within flushing devices for closet tanks, in which the the tank. usual levers, wires and flushing valves or balls As shown in Fig. 1, water normally rises in both are omitted and instead thereof a combined siarms of the siphon to the height designated by 5 phon and trap is employed disposed in the tank the numeral 1 in Fig. 1. Above the point 1 is an 5 so as to control the flushing thereof. air-lock 8 which connects both arms of the siphon The combined siphon and trap are preferably and extends downwardly therein to the surface made in one piece of a tube or pipe bent to form of the Water in the siphon arms. This air-lock the same for the sake of simplicity and cheapness holds the water in both arms of the siphon and 10 of manufacture. The structure has an air trap in the trap 4, and also holds the water in the 10 whereby the air locks the water in it and holds tank I at a point above the top of the siphon, the water in the tank up above the top of the p event ng flow of the Water through the siphon siphon until the air is released. The release of and trap until the air is released. The topof the the air in the air lock causes water to flow from Siphon is provided With a Valve 9 releasing the the tank to the water-closet bowl. A control air from the air-lock 8 to the atmosphere, which valve is connected with the air lock in the top of Valve 9 y be Controlled in any Suitable Way as the Siphon for the purpose of releasing the air by a handle l0. therefrom in order to start the flow of water. When e Valve 9 is p ned, it releases the air This flushing mechanism is practical, and may from the air-lock 8 in the siphon 5, creating a be manufactured cheaply because of its simplicity, ot in the open arm of th S p o u fi ient 20 and it is practically noiseless in operation. The to Start the w of Water through the p on and construction is such that it may be installed in the ap into the W Whieh ntinues until new or old tanks as desired and eliminates the practically all of the Water has been ptied from usual ball valve, wires and flush-levers ordinarily the tank, the emptying action being accomplished 25 employed quickly and practically noiseless.
